SPECIFICATION forming part of Letters Patent No. 768,521, dated August23, 1904. 'l Application filed December 6,1898. vSerial No. 698,410. (Nomodel.) i

T0 all whom, it may concern,.-

Be it known that we,v CHARLES H. CROWELL and EUGENE H. TAYLOR, citizensof the United States, residing at Lynn, in the county of Essex and Stateof Massachusetts, have invented certain new and useful Improvements inBookbinding-Machines, of which the following is a specification,reference being had therein to the accompanying drawings.

Certain classes of memorandum' or blank books, as4 well as other books,are stitched along the line of the fold and then have applied to theexterior of the fold a strip of gummed cloth or other material. Usuallyin practice, sofar aswe are aware, up to the `date of this our presentinvention the' operation of applying the gummed strips has beenperformed by hand. Machinery has been devised for the purpose; butV itis llarge an'd cumbrous, expensive, and. unsatisfactory in its working.&c. In making applicationA of the gurnmed strips a narrow strip ofsuitable cloth of continuous length' is taken. If this strip has beenprepared beforehand by `coating it with an adhesive, such as glue, it ismoistened to render it capable of adhering to the surface to which it isapplied. If not previously coated with an adhesive, then a suitableadhesive is applied thereto at the time of using it. In makingapplication of the strip by hand the strip either after or before havingbeen moistened or coated with adhesive in a moist state is cut intosections of the required length, and the respective moistened or gummedsections are applied to the books or the like which are in course ofbeing manufactured and are smoothed and pressed down into place. Thismode of performing the work is comparatively slow and expensive.

It is the object of our invention to provide a simple, compact, andinexpensive machine of large output which shall perform automaticallyand expeditiously the various operations which are required to beperformed in making application of the gummed strips, as aforesaid, forthe purposes of bookbinding and the like.

The invention consists in the improved machine which we will nowproceed-to vdescribe with reference to the accompanying drawings, inwhich last we have represented the best embodiment of the inventionwhich we have thus .far contrived. The invention first will be describedfully with reference to the said drawings in treating of the'saidembodiment thereof, after which the essential and distinguishingcharacteristics of the invention will be particularly pointedout anddistinctly delined in the claims at the close of this specification.

' Figure l of the drawingsl is a View showing in perspective a machinecontaining the embodiment aforesaid of our invention. Fig. 2 is a viewshowing the said machine in plan,

but with the work-supporting table removed in order to show parts whichwould be covered and concealed by the said table. Fig. 3 is a view of aportion of the machine in longitudinal'section, showing chiefly thefeeder and its actuating mechanism. Fig. I is a view in section on line4C 4 of Eig. 3 looking in thev direction that is indicated by the arrowsat the .ends of such line. Fig. 5 is aview showing in plan thefeeder-actuatingy devices of Fig. 3, the feeder itself being' omitted.Eig. 6 is a view, partly invertical section, looking from the far sideof the machine in Figs. 1 and 2 of the series of rollers, theirsupports, 'and their actuating mechanism. Figf'? is a `partial plan ofthe devices and mechanism Vvof Eig. 6. Fig. 8 is an elevation of themois- Atening or gumming devices. Eig. 9 is a partial elevation of thecutting devices.A Fig. l0 is a view in section on the line IO 10 of Fig.9, showing also two pairs of rollers.

The framework of the machine isshown ascomprising chiefly the bed 1, itslegs 2 2, (which may be replaced by other forms of supports,) and thetable 3, which last is located above the bed l, parallel with thelatter, land is supported and spaced therefrom in any suitable orconvenient manner, as by means of blocks or the like, herein designated4 4. The bed l serves to uphold or support the various working and otheressential parts of the machine, while the table 3 in the presentinstance serves chiefly to receive the blank when it is about to havethe gunnned strip applied thereto, to support and guide the blank as itis being delivered or fed by the action of the machine to the deviceswhich apply the gummed strip, and to support the feeder for the blank. i

5 designates a table or platform that is provided for the convenience ofthe operator who attends the machine. This table is located above theleft-hand side of the machine, as viewed in Fig. 1, and serves toreceive and hold a number of blanks, (each blank consisting of acollection of sheets stitched together and in readiness to receive thegummed strip.) The operator stands adjacent to this table and at theside of the machine which is turned to the front in Fig. 1 and taking ablank therefrom lays it on the upper surface of the table 3.

6 designates a feeder against the forward (left-hand) edge or surface ofwhich the blank is laid by the operator. The said edge or surfaceextends crosswise of the table 3, and to the said feeder is applied anend gage 7, against which last one end of the blank is caused to takebearing by the operator, the said end gage 7 being designed to 'positionthe blank properly, so that in the subsequent operations of the machinethe gummed strips shall be applied to the desired portion of the blank.The end gage 7 should be capable of adjustment along the feeder in adirection extending transversely with reference tothe width of themachine in order to provide for the handling of blanks of variouslengths. To this end it is made capable of movement upon the feeder inthe direction of the length of the edge or surface of the feeder,against which the side edge of the blank is caused to bear by theoperator, and it is secured in the desired position of adjustment uponthe feeder in some suitable or convenient manner-as, for instance, bymeans of the clamping-screw, which is designated 8.'

The devices by means of which the gummed strip is applied and caused tobecome firmly and closely attached to the blanks are located at theleft-hand side of the machine, as viewed in Fig. 1. For the purpose ofcarrying to the said strip applying and attaching devices the blankwhich has been laid in position against the feeder and end gage movementis communicated to the feeder. In the present case the feeder is causedto reciprocate in a plane that is parallel with the upper surface of thetable 3. Various arrangements for supporting and operating the feedermay be adopted in practice. For some reasons we prefer the arrangementwhich is shown in the accompanying drawings. In the said drawings thefeeder l6 is mounted on a slide-bar or carrier-bar 9, Figs. 2, 3, and 4,that is fitted to slide in Aguideways 10 10, which are provided at oradjacent to a slot 11, extending in the direction olE the length of thetable $3, at or near the mid-width ofthe said table. As a` means ofimparting reciproeating movement to the slide-bar 9 we connect to ablock 912. secured to the said slide-bar, one end ol a rod 12, Figs. 1,3, and 4, which last is joined also to a level` 13, the said lever beingvibrated at the proper times in the working of the machine by meanshereinafter to be described. At the left-hand end of the table 3 weprovide a series of pairs of rollers v17 1T, &e., Fig. 6, the rollers ofeach pair being separated from each other to an extent sullicient topermit of the entrance of the blank between them. The first pairof theserollers receives the l'orward edge of the blank as it is moved towardthe rollers by the feeder, and by the relation of the rollers the blankthen drawn in between the rollers and fed from one pair ol rollers tothe next in succession through the series until it is linally dischargedfrom the last pair of rollers. A table 171, l `igs. 1 and 2, may bevprovided to receive the blanks as they pass away from the last pair olrollers. In order to tit the machine for use in connection with blanksof different thicknesses, we make provision for varying as required thespaces between the rollers of the respective pairs. We effect thisconwniently b v rendering the upper rollers of the respective pairsadjustable toward and from the lower rollers of said pairs. In thepresent instance the boxes or bearings 13 18 for the upper rollers areall applied at cach end ol the set of rollers to a head 19, which iszuljusliahle vertically with reference to the lower rollers. 2O 20designate screws which we show for the purpose of enabling the verticaladjustment of the heads 19 19 to be el'lected when it is desired torender the distance separating the upper set of rollers from the lowerset ol rollers suitable to the thickness of the blanks. Vile employ twoadjusting-serews in connection witheachhead 19, the said screws littingthreaded holes or openings which are made through projecting portions 2121 of the head and plain portions of the stems of the screws beingfitted to bearings in upwardlv-extending portions of the adjacent lixedhead 2L), Fig. 1. The lixed heads Q2 22 are bolted to the bed 1. Tocouple the two adjnstilig-screws 20 for each head 19 together, so thatboth ends of the said head shall beadjusted in unison and to the sameextent, we attach to each screw 2O a bevel-gear 23, and in bearings 24;24, applied tothe said upwardlvextending` portions of the correspondinglixed head 22, we mount a shaft 25, extending at right angles with therollers 17'17, the said shaft Z5 having fast thereon bevel-pinions 2li2t in mesh with the bevel-gears 23 23. ',lhe sha l't 25 has thereon alsoa haml-wheel L17 or its equivalent. By turning the shalt 25 b v means ofpower applied to the said hand- IOS lIO

wheel the screws may be rotated, and the head thereby adjusted asdesired in order to place the upper and lower feed-rollers 17 17 at theextent, and the two adjustable heads 19 19 areV adjusted simultaneously,both to the same extent. Thus we have shown in Fig. 2 (but for the sakeof clearness lhave omitted from Fig. 1) a shaft 28, extending from onead- .justable head 19 to the other, the said shaft 28 being supported byone of the bearings 24 at each side of the machine and having affixed toits opposite ends bevel-pinions 29 29, meshing with two of thebevel-gears 23 23. The described arrangement causes simultaneousadjustment of both of the movable heads 19 19 to be effected whenevereither of the shafts 25 is rotated by means of its. hand,- wheel.

For the purpose of driving the feed-rollers 17 17 each of the latter hasfast on each end thereof a spur-pinion 30. Ihe lower feed- 'rollers areall connected together, so as to cause them to rotate in unison by meansof idle or carrier pinions 31 31, which are supported onthe fixed heads22, the said pinions 31 being in mesh with the Vpinions 30 on the saidlower feed-rollers. Similarly the upper feed-rollers are connected torotate in unison by means of carrier-pinions 32 32, which are mounted onthe adjustable heads 19, the said Apinions 3 2 being in mesh with thepinions 30 on the said upper feed-rollers. For the purpose` of drivingthe various pairs of feed-rollers bevel-gears 33 33 are made fast on theupper and lower rollers, respectively, of one pair of the saidfeed-rollers, andI like bevel-gears 34 34 are mounted on a verticalshaft 35 at the side of the machine. 'Ihe lower bevel-gear 34 is madefast on said shaft 35, while the upper bevel-gear 34 is splined thereto,these bevelgears 34 34 meshing, respectively, with the bevel-gears 3333, which are mounted, as aforesaid, on the said pair of feedrollers.The said vertical' shaft 35 is fitted to bearings 36 and 37, which aresecured to respectively vthe box 18 for the first upper feed-roller andthe fixed head 22 at the side of the machine on which the said shaft islocated. The bearing 36 moves up and down along the shaft 35 as the saidadjustable head 19 is Iadjusted. Vertical support is afforded the shaft35 by reason of the fact that the lower bevel-gear 34 y rests on theupper side of the bearing37, af-

fixed to the iixed head 22. On the lower end of the vertical shaft 35 ismade fast a bevelgear 38, which is in mesh with the bevel-gear 39 Von ahorizontal shaft 40, which is driven by bevel-gears 41 41'from' theVmain or driving shaft 42 of the machine.

In orderI to compensate automatically for differences in the thicknessof the blanks which pass between the upper and lower sets of feedrollersand for inequalities in the said blanks, the boxes or bearings 18 18 forthe upper feedrollers are made movable vertically in the recesses 43 43in the adjustable heads. (See Fig. 6.) The said lboxes or bearings areprevented from descending too low by means of the cap-plate 44, which issecured to the under side of each adjustable head 19 and bridges thesaid recesses. The boxes or bearings 18 18 when in their lowestpositions in the vsaid recesses 43 43 are supported bythe cap-plates 4444. They are pressed toward the said plates, so as to carry the upper set offeed-rollers toward the lower sety by means of springs 45 45, whichare compressed within the recesses and act downwardly against the topsof the said boxes or bearings 18 18.'

lAs theblanks are presented successively to the feed-rollers by theaction of the feeder they encounter the gummed strip, the latter havingbeen prepared for application thereto. The gummed strip in a continuouslength is guided so as tobecome applied to the portion of each blankwhich it is desired shall receive the same, and the said continuouslength of gummed strip passes or advances through the series of pairs offeed-rollers in unison with the blanks and attached to the latter. It ispossible to introduce the gummed strip from above and to apply the sameto those portions of the blanks which are turned upwardly. It enables abetter and more convenient arrangement of the parts of the machine to besecured, however, to introduce the said. gummed strip into thefeed-rollers from below and to apply it to portions of the blanks whichare at the under. sides of the latter. We have therefore in the presentcase arranged to introduce the gummed strip from below. The said striptherefore lpasses in between the first pair of feed-rollers below theblanks, which are carried forward to the said feed-rollers by the actionof the feeder, and bythe compression of the successive pairs offeed-rollers the gummed stripis caused to become firmly united to theblanks. In order to insure that the gummed strip shall be pressed intoclose and intimate contact with -all portions of the surfaces of theblanks, we cover the lower feed-rollers with rubber or other elasticmaterial, as at 46 46, Fig. 10..

47 designates a roll of material in strip form, the same being wound ona reel 48, the shaft of which latter is supported in bearings 49inbraokets 50,carried by the lower part of the machine-frame. 51 is abrake-wheel that is fast on the said roller, and 52 is a weightedlbrake-band'in contact with the saidbrake- -wheel and cooperatingtherewith toI act, as a IOO IIS

drag to prevent the too free unwinding of the strip from the roll. 58,Figs. l and 8, is a trough. 54 is a cylinder or roller which is mountedabove the said trough, with a portion of its surface dipping into thelatter. 55 and 56 are guide-rolls on opposite sides of the said cylinderor roller 54, and 57 is the support on which the said trough, cylinder,and guiderollers are mounted. From the supply-roll 47 the strip passesover the guideroller 55 and the cylinder or roller 54, under and partlyaround the guide-roller 56, and thence to the feed-rollers 17 17. If thematerial contained in the supply-roll 47 is in the form of apreviously-gummed strip, then the trough 53 contains water, and thewaterwhich is taken up by the surface of the cylinder or roller 54 istransferred to the gummed surface of the strip as the latter travelsover the cylinder or roller. It' the material in the supply-roll 47 isin an ungummed condition, then the trough 53 will contain a suitableadhesive, and the saidadhesive will be applied by the cylinder or rollerto the'strip as the latter advances to the feed-rollers.

571 is a scraper or doctor working in connection with the surface of thecylinder or roller 54 and operating to remove therefrom the excess ofwater or adhesive taken up by the peripheryotl the said cylinder orroller 54. The said scraper or doctor is journaled in the support 57 at572, and from one of its journals projects the arm 58. A hole in thefree end of this arm receives a threaded stud or bolt 59, projectingfrom the said support 57, and a spring 60, surrounding the stud 59 abovethe arm, acts with a tendency to bear the doetor or scraper 58 towardthe periphery of the cylinder or roller 54. A nut 61 on the said stud 59below the said arm 58 serves as an adjustable means of limiting theapproach of the doctor or scraper to the said periphery.

In some cases we contemplate allowing the series or' blanks to bedischarged from the last pair of feed-rollers while remaining `stillconnected by the continuous strip, the disconnectionor separation of theblanks from one another being effected subsequently. Usually, however,we shall combine with the feedrollers cutting devices operating to severthe strip between successive blanks, thereby separating or detaching theblanks from one another.

62 and 63 (see, for instance, Figs. 9 and 10) designate, respectively, aiixed cutter and a moving cutter which in the illustrated embodiment ofour invention we locate intermediate the discharging pair offeed-rollers and the pair of feed-rollers next preceding the same. Bythe closing of the said movable cutter against the said fixed cutter theseverance of the strip between each two blanks is eiected, so that asthe blanks pass out from between the dischargingv pair or' feed-rollersthey are disconnected and separated. The cntters act as customary insimilar connections to occasion a shearing eut. This consumes,ordinarily, an appreciable period of time in its accomplishme1it---thatis to say, although the actual cutting operation is in reality performedvery quickly and in an exceedingly small fraction oli time, there is,nevertheless, a period or' time between the instant when the cuttersclose upon the gummed strip between two blanks and the instant when thecomplete severance of the said gununed strip is elected, which period isso short that it hardly admits of being measured and yet is or' suchduration that the hold of the cutters upon an incompletely-severedmoving` strip would or might occasion an objectionable drag, this dragacting in opposition to the pull of the feeding-rollers which `succeedthe cutters in the line of travel of the blanks. l `urthermore, duringthe time that the cutters are closed together and until theysubsequently have be come separated sulliciently they are in position toconstitute an obstruction in the path ol the portion oi: gummed stripwhich is advancing` toward them or in the path ol the advancing blankwhich is nearing them. No dilliculty in lthese respects will beexlierienced when the machine is being run at a. low rate of speed andwith contin uously-rotating feed-rollers or even when the machine isbeing run at a iairly high rate or' speed with eontinuously-rotatingfeed-rollers, provided the blanks do not succeed one another too closelyin passing through the feed-rollers, nor when the feed-rollers areactuated with an intermittent motion, as contemplated by us in somecases. \V e desire that the machine shall be prepared and litled in allrespects to yield a large output oi work, and the machine is, in tact,intended to be worked at a rate oi speed which shall be limited only bythe capacity oi" the operator to place the blanks successively in properposition upon the table 3 against the feeder 6 and the end gage 7.'lherei'ore we prefer to em* ploy continuously-operating feed-rollers,i11- asmuch as they are litted ior a greater output, and in order toenable such feed-rollers to be utilized advantageously we make provisionin the shape of means whereby at the time oi the closing of the cuttersthe said cutters are advanced in unison with the travel of the blanksand gummed strip. This obviates any drag on the partially-severed gummedstrip. lt obviates any tendency to obstruct the path oli tlie'gummedstrip or blanks. ,lt also enables the successive blanks to be spacedmore closely together than would otherwise be possible, and therebyenables a considerable economy to be effected in the amount of gummedstrip which is consumed by reducing the distance between adjacentblanks, and consequently reducing the length oi the portions o1 gummedstrip intervening between the blanks, such portions having subsequentlyto be trimmed oli`, and hence being olt course wasted. l e

lOO

show hereinfor the purpose of actuating the cutters a rock-shaft 64,extending across the machine beneath the feed-rollers and mounted inbearings in the fixed heads 22 22. At each side of the machine we clampupon the said rock-shaft, near to the end of the latter, an arm 65. Thetwo arms 65, which together form a carrier or support for the cutters,have secured Ato them the fixed knife-bar 66, it having attached theretothe lower cutter 62. The said arms are formed with guideways, receivingthe end ofthe upper or moving knife-bar 6,61, to which last is'attachedthe upper cutter For the purpose of causing the movable cutter to bemoved toward and from the fixed cutter we join the movable knife-bar6611by short links or connections 67, Fig. 10, to arms 68 68 on arock-shaft 69, the said rock-shaft beingv supported in bearings that areformed in projecting portions of the arms 65. The arms 68 are connected,respectively, by links 681 681 to arms 691 691, made fast on a secondrock-shaft 692, which is mounted in bearings on the arms 70 70, whichare made fast on the ends of the rack-shaft 64. The free extremities ofthe arms 70 70 have attached thereto the free extremities of the arms 6565, so as to afford support to the latter and prevent the cutters fromspringing with relation to each other. On one end of the said rock-shaft692 is an arm 71, (see Figs. 1 and 2,) which is connected by a rod 72with the lever 73, which last is pivoted to the table 1 at 731, Fig. 1,and

moved at the required times in the operation of the machine to efect thecutting ofthe portions of gummed strip connecting Successive blanks. Forthe purpose of causing the cutters at the time of the cutting operationto advance in unison with the travel of the blanks and gummed strip thecutter-supports in the present case are swung around the axis -ofrock-shaft 64. This is eected by imparting movement to the arms 65 and70. Herein the arm 70 is shown connected by a rod 74 with an arm 7 5,pivoted upon lever 73. At the time when lever 73 is moved to close thecutters the arm 75 is acted upon by a suitable moving device, asexplained hereinafter, to press it toward the left in Figs. 1 and 2,thus moving the cutter-supports and cutters in the same direction, thisbeing the direction of the feed of the gummed strip and blanks, while aslever 73 is moved to open thecutters again the arm 75, cutter-supports,and cutters are permitted to swing' back into their original positions.

The feeder 6 has been described herein as connected by rod 12 with thevibrating lever, 13, Figs. 1, 3, and 4. As a means of vibrating thelever 13 we show herein a cam 14, Figs. 3 and 5, the said cam having aslot 15, which receives a pin or roller 16, carried by the lever 13. Thecam 14 constitutes an actuator for the feeder. It is arranged andconstructed hereinto have an intermittent motion and also toreciprocate, so as by the movement thereof in one direction to advancethe feeder and by the movement thereof in the other direction to returnthe feeder to. its starting position. Cam 14 herein reciprocates orrocks about an axis, 'it being shown herein fast upon a rock-shaft 7 6,to which latter is applied the power by means of which the cam is movedto advance the feeder. The rock-shaft and cam are held normally in theposition in which they are shown in Figs. 3 and 5, which correspondswith the normal retracted position of the feeder, and are returned tothat position after having been actuated to advance the feeder by meansof a spring 77, one end of which is connected to a screwthreaded bolt78, that is applied to a threaded hole in a depending iiange of bed 1ofthe machine, the said bolt having a check-nut 79 applied thereto. Tothe other end of the said spring 77 is connected a strap, as 80, whichextends from the spring to and is wound around a convenient portion orattachment of the shaft 7 6-as, for instance, the hub of the cam 14-theend of the said strap being attached to the said hub. An adjustablestop,

as 81, herein constituted by a screw set in a convenient portion of thebed, is engaged by a projecting part, as 82, of the cam 14, and therebydetermines the position to which the .cam and the parts which areoperated therefrom are returned by the action of the spring 77. For 'thepurpose of rocking the shaft 76 and cam 14 in order to cause the feeder6 to be advanced I apply to the said shaft 76 the members 83 and 84 of aclutch, the latter beingv herein constituted conveniently by a wellknownform of friction-clutch. The member 83 is free to turn on the said shaftand has combined or connected therewith a spurgear 85, meshing with aspurgear 86,'fast on the driving-shaft 42. The said member 83 thereby isrotated continuously from the said driving-shaft. The member 84 of thefriction-clutch is splined to the shaft 76. LNormally it is disengagedfrom the member 83. It is moved along shaft 76 by a shifting or closingmeans, herein constituted of a lever 87, which is pivoted to the bed ofthe machine, one arm of the said lever carrying a fork 88, which entersagroove 89 in the hub of the member 84, and the other arm of the saidlever carrying a pin, roller, or other projection 90, which lies in thepath of rotation of a cam projection 91 on a hub 92 of shaft 93. In therotation of the shaft 93 the cam projection strikes the pin, roller, orother projection aforesaid and turns the lever so asv to press themember 84 of the friction-clutch into engagement with the member 83.This locks the member 83 to the shaft 76, so as to cause the ysaid shaft76 and its cam 14 to be turned through the driving connection of IOO IIO

IIS

member 83 with the main driving-shaft, thereby occasioning through theconnections which have'been described an advance of the feeder 6. Thecam projection 91 immediately passes away from the pin, roller, or otherprojection on the lever 87, permitting the member 84 of thefriction-clutch to move sufficiently from the rotating clutch member 83to become disconnected therefrom, whereupon the spring 77 occasions thereverse movement of the cam 14, shaft 7 6, and feeder. kThe said camprojection we designate the controlle1cam,inas much as it controls theworking of the feeder. To prevent movement of the member 83 of thefriction-clutch lengthwise of the shaft 7 6 when the splined member 84is pressed against the said member 83, a collar, as 94, is placed uponthe said shaft 76 at the side of the clutch member 83. The shaft 93 isrotated from the main or driving shaft 42 by suitable gearingconnections, herein shown as comprising a pinion 95, Fig. 1, on the saidmain or driving shaft 42, a gear 96 on the shaft 93, and intermediate,idle, or carrier gears 97 and 98, Figs. 1 and 2. For the purpose ofoperating the lever 73 we mount a cam-disk 99 on the shaft 93, the saidcam-disk being formed with acam-slot, as 100, receiving a pin or roller,as 101, which is carried by the lever 73. For the purpose of operatingthe arm 7 5 we mount a cam 102 on the shaft 93, the said cam actingagainst a pin or roller 103 on the said arm 75.

It will be observed that the feed-rollers are operated by drivingconnections intermediate the same and one rotating shaft in the machineand that the actual movements of the feeder are communicated to thelatter through intermediate operating devices from the same shaft. Alsothat the time of working of the said feeder and the times at which thevertical and horizontal movement of the cutting devices shall take placeare determined by cams on a second rotating shaft of the machine. Thissecond shaft in virtue of the control which it exercises over theWorking of the feeder and cutting devices may be termed a vmaster-shaft.It will be obvious that by varying the speed of rotation of the secondor master shaft 93 relative to the speed of rotation of the shaft 42 thetiming of the feeder and cutting devices may be varied to suit blanks ofany desired length. For longer blanks the shaft 93 will be required torotate more slowly relatively to the shaft 42, and vice versa. In orderconveniently to vary the speed of the shaft 93 relatively to that of theshaft 42, we provide for the use of change-gearing by making one or bothof the carrier-gears 97 and 98 replaceable by others of differentdiameters. The stud on which the said change-gears are mounted is fixedto an adjustable carrier or bracket, as 104, as customary in the case ofchange-gears.

ln adapting the machine for a given width of blank the feeder (i isshifted on iis carrierbar 9 toward or from the feed-rollers. ln order toenable the shift of the feeder upon the said carrier-bar 9 to be madewhenever desired, the said carrier-bar is formed in the direction of itslength with an undercut slot 109,-Fig. 4, and through therearwardly-projecting part of the feeder is passed the stem of a bolt110, the latter having its head seated in the said undercut slot beneaththe overhanging side edges of the slot and the stem of the boltreceiving the wing-nut or clampnut 111.

In some cases it is desired to unite a continuous gummed strip to oneside. of a continuoussheet of paper or other material. 'lo enable thisto be accomplished with the aid of our machine at such times as themachine is not employed for applying the gummed strip tomemorandum-books or similar blanks, we apply to the right-hand end ofthe niaehine in Figs. 1 and 2 brackets 105 105 to receive the journalsof a guide-roller 100. 'l`o the legs 2 2 we apply brackets 107 107,having` bearings to receive the journals of a roller 10S, containing orhaving wound thereon the continuous sheet of paper or other material towhich it is desired to apply the gummed strip. 'lhe said sheet of paperis lcd over the guide-roller 106 and in the direction of the length ofthe table, it then being passed between the rollers of the successivepairs of feed-rollers in company with the gunmied strip`v lVhen themachine is utilized for this purpose, the feeder and cutters arerendered inoperative by disconnecting the gearing, which is locatedintermediate the d riving-shaft and the shaft 93. By leaving the cuttersin action the sheet may be divided into short lengths of any requiredsize, the size thereof being provided for through the proportions of thegearing which rotates the cutter-operating cam.
